1) first picture, i downloaded folder through hfs, there are some trush instead russian letters
you are right, there's a problem.
I spent the last 30 minutes understanding it.
Apparently Total Commander reads these files correctly, while winrar and 7zip don't.
I guess winrar and 7zip are more standard.
HFS is using ANSI to encode filenames, while Winrar and 7zip are using OEM.
I guess HFS will have to comply with them.
I put this in the to-do list.
There's nothing you can do for now, sorry.
2) second pic, DMaster is downloading a folder with mp3 music, the extention of file is *tar, why not *rar? when its finished, folder is still like - folder.tar, winrar dont recognize that archive, what is the extention *tar?
it's a totally different archive format, like zip.
I used tar because it was easier for me to make.
